Answer:
m∆IED= 83°
m∆JFG= 87°
Step by step
m∆IED is 97° so if you subtract 97 from 180(a straight line) you would get 83°
and the same for m∆JFG if you subtract 93 from 180 you get 87°

Answer:
Difference between Observational and Experimental Data
The data collected in the study is observational data.
Step-by-step explanation:
In an experimental study, the data collected is divided into two groups. One group is the control group. The other group is the treatment group (also known as the experimental group). Data is gathered about the groups in order to compare their different outcomes and to draw conclusions if there is any causality based on the two variables. With observational data, the researcher is interested in observing the variables to determine if there is any correlation.
